MACHINE FOR COATING PAPER.

Specifidation of Letters Patent.

Patented June 25, 1907.

Application filed September 28, 1906. Serial N0- 336.657.

To aZZ whom it may concern.-

Be it known that I, MARTIN CANTINE, of Saugerties, Ulster county, New York, have invented a new and Improved Machine for Coating Paper, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, in which Figure 1 is a side elevation of my improved machine; and Fig. 2 is an end elevation thereof.

The purpose of myinvention is to provide means for coating paper, and the machine which I have invented for that purpose accomplishes the work in a very efiicient manner and its simplicity of construction renders it of especial advantage. The coating is applied for the purpose of surfacing the paper to prepare it for printing or lithographing.

In the drawing, 2 is a color roll which is driven by a chain 2 or otherwise, and rotates in a color box 3. It is provided with a skimming plate or doctor 4, whose edge is nearly in contact with the surface of the roll so as to skim the color therefrom 'and to deliver it upon the surface of a lower roll 5, preferably felt-covered, and geared to a companion roll 6, one of these rolls being driven bya sprocket chain or belt 7 from a cone pulley 8 or other means may be employed to drive these rolls at a variable rate of speed. The driving mechanism of the roll 2 is also variable so as to regulate the rate of delivery of the color.

6 1s a color box by which the color is applied to the roll 6.

13 is a color pump, which communicates with a color tub 14 and lifts the color to the boX 3, from whence it is discharged to a suitable overflow into the box 6, whence it overflows into the tub 14, thus maintaining a constant fiow and agitation of the color.

12, 12 are rotating brushes, and 11, 11 are reciprocating brushes which are adapted to smooth the color applied by the rolls and rotating brushes.

In the operation of the device, the paper is drawn from a web 9 and passes over a guide roll 10, from which it passes in a horizontal plane between the rolls 5, 6, the rotating brushes 12, 12 and the reciprocating brushes 11, 11. The color is applied to the upper surface of the paper by the roll 5, which receives its color from the doctor 4 and is also applied to the lower surface by the roll 6. The brushes 12, 12, being in contact with the rolls 5 and 6, receive the surplus color there from and apply it in a second coating to the web of paper on the top and bottom thereof, and when the paper passes between the brushes 11 the color is smoothed. From the brushes 11 the paper is drawn by suitable draft rolls to and throu h drying mechanism of the usual variety. If desired, the rotating brushes 12 may be placed on the front side of the color rolls 5 and 6 and in contact with it,

in which case they will apply the first coating of color to the paper.

Within the scope of my invention as defined in the claims, the parts of the apparatus may be modified and other means than those shown may be used for delivering the color to the rolls 5 and 6, since What I claim is:

1. Apparatus for coating paper, having color rolls between which the paper passes, means for applying the color to the rolls, and rotating brushes in contact with the rolls and adapted to receive color therefrom and to apply it as an additional coating to the paper. 2. Apparatus for coating paper, having color rolls between which the paper passes, means for applying the color to the rolls, and rotating color applying members in contact with the rolls and adapted to receive color therefrom and to apply it as an additional coating to the paper.-

In testimony whereof, I have hereunto set my hand.
